Laws of exponents:
(a^x)^y=a^(xy)
a^0=1 (a≠0)
Therefore
(7^13)^3.7^0
=(7^(13*3)). 1
=7^39
To find the area you would had to do a an triangle formula so the final answer would be 63 inches
70. 180-120=60, and 180-60+50=70
Answer:
It is given that : 
As we have to find the Domain of
.
-1 ≤ sin x ≤1

So it is defined for x lying between
.
As meaning of Domain is those values of x for which any function f(x) is defined.
Probability theory, a branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be any one of several possible outcomes. The actual outcome is considered to be determined by chance.
